HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 447,115, dated February 2 1, 1891.

Application filed May 24, 1890. Serial No. 352,974. (No model.)

To all whom, it may concern.-

Be it known that I, HARLEY INGERSOLL, of the city of Lansing, county of Ingham, and State of Michigan, have invented certain new and useful Improvements in Heating Devices, of which the following is a specification, referenee being had to the accompanying drawings.

The object of my invention is to provide means, in a heating-drum or the like, of taking up and radiating the greatest possible amount of heat generated by a given source. To do this I employ,in combination with a source of heat, a bundle of wire or any such substance which is meshed or tangled, so that the flame or heated air may pass through the substance, and that each strand or fiber may be heated thereby.

In the accompanying drawings, Figure l is a perspective view of my improved heater provided with an ordinary lamp having part of the shell of the drum broken away to expose the interior. Fig. 2 shows a frame adapted to carry the bundle of wire. Fig. 3 shows the frame with a portion of the wire wrapped around it.

Referring to the letters upon the drawings, A indicates a hollow metal shell or drum. It may be made of sheet or cast metal, but preferably the former, and may be fashioned in any shape or size. It may be supported by legs B, which carry near their lower ends the shelf C. This shelf may carry upon top of it a lamp D, which may be of any ordinary construction, that kind which gives the most heat being preferable. For convenience a circular space maybe cut into the shelf 0 and the lamp set into it just like an ordinary hanging lamp.

The legs, the shelf, and the lamp are illustrated for the purpose of showing a convenient and desirable form of embodiment of my invention; but I desire to have it understood that any suitable source of heat may be employed-instead of that illustrated.

\Vithin the shell or drum, at a suitable distance above the source of heat, upon internal projections E, is carried, preferably upon a frame F, a bundle, say, of wire G, which completely fills the space over the source of heat, but allows the flame or heated air to pass upward through it and heat the entire mass. The bottom of the shell is-open, and the top is perforated at H, so that a constant current of air is kept up through the woven mass.

The bundle which I employ for the purpose of retaining the heat I form by taking strips of metal, preferably wire, and, wrapping it around the frame F, alternating the direction .in which I wind it, so as to form a regularly- HARLEY INGERSOLL.
